INSTALLATION AND OPERATION GUIDE
As you set the temperature, the
outer ring lights up turning the dial.
As the water heats up, the color
fills in the white lines based on the
power percentage.
Once trutankless reaches the set
point, the center lights up.
SETTING/ADJUSTING THE OPERATING TEMPERATURE
The trutankless unit comes preprogrammed for an initial temperature setting of 120°F (49°C). This set point can be
changed via the Temperature Controller on the Home screen from 90°F to 140°F (32°C to 60°C), in single digit increments.
Properly used, the trutankless Water Heater will deliver the desired temperature, even when the water flow varies, or
when more than one hot water tap is open.
In multiple unit configurations, each controller can be individually programmed, but the heater can only deliver one water
temperature at a time. Should the demand for hot water (flow) exceed the unit’s capability, there will be a corresponding
decrease in the temperature of the water delivered.
The Controller utilizes a touchscreen rotary adjustment.
Touch the indicator arrow and drag clockwise (right) to INCREASE the temperature;
drag counterclockwise (le) to DECREASE the temperature.
*These temperatures are only suggestions. You may use higher or lower temperatures to suit
your needs. Remember that maintaining lower hot water temperatures will save additional
energy. The eiciency of the heater is not aected by mixing in cold water at the point of use
because the trutankless will simply detect a lower flow through the heater and adjust the
power accordingly. Most users find a happy medium by setting their unit at 120°F.
*Suggested Temperature Settings:
Kitchen: 110°- 130°F (43°- 54°C)
Shower: 98°- 114°F (36°- 45°C)
Bath: 102°- 110°F (39°- 43°C)
0˚- 110˚F 110˚- 130˚F > 130˚F
The color of the dial is coded to change to visually indicate the temperature of the water.
